Answer: The correct answer is A

Step-by-step explanation:

If your multiplying fractions you take the first fraction 1/4 and the number 5, but you turn that into a fraction so now it's 5/1, and you multiply them together to get 5/4

1/4 x 5/1 = 5/4

Answer:

Step-by-step explanation:

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ = 16.4

For the alternative hypothesis,

µ ≠ 16.4

This is a 2 tailed test

Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = population standard deviation

n = number of samples

From the information given,

µ = 16.4

x = 17.1

σ = 3.1 feet

n = 31

z = (17.1 - 16.4)/(3.1/√31) = 0.89

The calculated test statistic is 0.89 for the right tail and - 0.89 for the left tail

Since α = 0.01, the critical value is determined from the normal distribution table.

For the left, α/2 = 0.01/2 = 0.005

The z score for an area to the left of 0.005 is - 2.575

For the right, α/2 = 1 - 0.005 = 0.995

The z score for an area to the right of 0.995 is 2.575

In order to reject the null hypothesis, the test statistic must be smaller than - 2.575 or greater than 2.575

Since - 0.89 > - 2.575 and 0.89 < 2.575, we would fail to reject the null hypothesis.

Therefore, this information does not suggest that the storm is (perhaps temporarily) increasing above the severe rating

The ordered pair(5,-3) is a solution to which of the following inequalities? a. y≥−2x+8 b. −2y<3x−9 c. y−2x>5 d. 4y+2x≤−1

stiks02 [169]

Answer:

Option d. $4y+2x\leq -1$

Step-by-step explanation:

we know that

If a ordered pair is a solution of an inequality, then the ordered pair must be satisfy the inequality

Verify each case

case a) $y\geq2x+8$

we have

$x=5, y=-3$

Substitute the value of x and the value of y in the inequality and then compare the results

$-3\geq2(5)+8$

$-3\geq18$ -----> is not true

therefore

the ordered pair is not a solution

case b) $-2y$

we have

$x=5, y=-3$

Substitute the value of x and the value of y in the inequality and then compare the results

$-2(-3)$

$6$ -----> is not true

therefore

the ordered pair is not a solution

case c) $y-2x>5$

we have

$x=5, y=-3$

Substitute the value of x and the value of y in the inequality and then compare the results

$-3-2(5)>5$

$-13>5$ -----> is not true

therefore

the ordered pair is not a solution

case d) $4y+2x\leq -1$

we have

$x=5, y=-3$

Substitute the value of x and the value of y in the inequality and then compare the results

$4(-3)+2(5)\leq -1$

$-2\leq -1$ -----> is true

therefore

the ordered pair is a solution
